Best practice to start/stop nodes in a cluster

General
1

we have cluster with multiple nodes. is there any best practice or sequence to start or stop nodes in a cluster by their type for version Pega’23.

in earlier version.

Nodes should be started in the following order:

  1. Primary search node
  2. Secondary search nodes, after the primary node has started
  3. Remaining nodes

Based on the discussion here, its mentioned that a Pega infrastructure specialist mentioned there points to follow during startup:

Bring Up:

  • Background Node 1 (BackgroundProcessing, Search, Stream, WebUser)
    • use the Web UI to verify the search index has finished building before continuing. I have not found a way to programmatically confirm search is finished building
  • Background Node 2 (BackgroundProcessing, Search, Stream)
  • Decisioning Node 1 (DDS, ADM, RTDG, Batch, RealTime)
    • You must have port 7000 open for Cassandra but it is not in the documentation
  • Decisioning Node 2 (DDS, ADM, RTDG, Batch, RealTime)
  • Decisioning Node 3 (DDS, ADM, RTDG, Batch, RealTime)
  • Web Node 1 (WebUser)
  • Web Node 2 (WebUser)

Bring down in the opposite order.
